Defining Overtravel 83
To configure the Overtravel page, make entries in the following fields:
Hard Travel Limits
Select this to use travel limit switches.
Note: If you select this, the action selected in the Fault Action page for
Hard Overtravel will occur when axis travel touches a travel limit
switch, thereby causing a Hardware_overtravel_fault .
Limit Switches
If you are using overtravel limit switches, select whether the limit switch
contacts are:
Normally Open
Normally Closed
Note: Your selection applies to both limit switches for a physical axis.
Soft Travel Limits
Select this to use software travel limits.
Note: If you select this, the action selected in the Fault Action page for
Soft Overtravel will occur when a software travel limit is
reached, thereby causing a Software_overtravel_fault .
Maximum Positive
If you selected Soft Travel Limits, type the positive direction software
travel limit.
!
ATTENTION: In addition to setting hard and soft
overtravel limits, hardwire the overtravel limit switches
and/or the CPU watchdog contacts into the drives so
that drive power is interrupted if a fault occurs.
Otherwise, unpredictable motion can occur.
